How to Read SmartTrak AWD Codes

The all-wheel drive, or AWD, on the Oldsmobile Bravada sport utility vehicle is constant and does not need driver interaction to switch it from two-wheel to four-wheel drive like some older types of all-wheel drives. SmartTrak is the proprietary name for this AWD system in the Bravada. The onboard diagnostic code system on the Bravada AWD will activate a check engine light if there is a problem the driver should know about. To attain the trouble codes for the Bravada, a code scanner tool is used. Practically all auto parts stores have these hand-held scanners available for use for free.

Instructions

1

Park the Bravada on a flat and level surface and engage the parking brake.

2

Kneel down on the outside of the driver's side door, and look under the dash to locate the diagnostic plug port. It is a small, black rectangle with a small cover on it marked "DTC" for Diagnostic Trouble Code. Remove the cap and plug the scanner wire into the port.

3

Turn the key to the "On" position but do not start the engine. Turn the scanner on and press the "Run Test" button.

4

Copy down the trouble codes given by the computer with a pen and paper. Turn the scanner off and unplug it from the port. Replace the port's cover. Turn the key off and remove it from the Bravada's ignition.

5

Look up the codes in the owner's manual or have the auto parts store attendant run the codes through the store's computer system to pinpoint the exact problem.
